Description

Technical Field

[0001] This invention relates to the field of horizontal machine tool technology, and specifically to a multi-axis positioning device and method for a horizontal machine tool tool post. Background Technology

[0002] In the operation of horizontal machine tools (such as horizontal gear hobbing machines, horizontal profile mills, and similar structures), the tool holder sometimes needs to rotate at a certain angle. Taking a gear hobbing machine as an example, a gear hobbing machine can cut spur gears, helical gears, and also process worm gears, sprockets, etc. It is a gear machining machine tool that uses a hob to process spur gears, helical gears, herringbone gears, and worm gears using the generating method. When switching to process different types of gears, the gear hobbing machine needs to rotate the tool holder at a certain angle. Therefore, the tool holder is usually fixed on a rotating base, and the rotation of the rotating base drives the tool holder to rotate to the required angle.

[0003] To ensure machining accuracy, the rotation center axis of the rotating base needs to be orthogonal to the rotation center axis of the tool spindle of the tool holder, and the rotation center axis of the rotating base needs to maintain a certain design distance from the center position of the tool on the tool holder. Once the tool holder is fixedly mounted on the rotating base, it forms a complete tool holder assembly. When the entire tool holder assembly is installed on the machine tool for use, the relative position between the tool holder and the rotating base cannot be adjusted. Therefore, precise positioning between the tool holder and the rotating base is required during assembly to ensure machining accuracy. However, currently, there is no device on the market specifically designed for precise positioning during the assembly of the tool holder and the rotating base. Summary of the Invention

[0004] To address the aforementioned technical problems, this application provides a multi-axis positioning device and method for a horizontal machine tool tool post.

[0005] In a first aspect, this application provides a multi-axis positioning method for a horizontal machine tool tool post, including: The rotary seat is placed horizontally, and the first positioning component is assembled onto the rotary seat so that the first spindle in the first positioning component is in a vertical state. Place the tool post spindle on the rotary seat, and tighten the connecting screw between the tool post spindle and the rotary seat to the first locking degree; The second positioning component is assembled onto the tool holder spindle, so that the second spindle in the second positioning component is in a horizontal state; Raise the first mandrel and adjust the position of the tool post spindle so that the slot at the upper end of the first mandrel can be inserted into the second mandrel so that the first mandrel and the second mandrel are orthogonal. Tighten the connecting screw to a second tightening level, which is greater than the first tightening level; Adjust the position of the tool holder spindle so that the end face of the second receiving plate in the second positioning assembly abuts against the outer circular surface of the slot, so that the actual distance between the rotation center axis of the rotary seat and the tool center of the tool holder spindle meets the design distance; Tighten the connecting screw to a third tightening level, which is greater than the second tightening level, and the third tightening level is fully tightened.

[0006] Disassemble the first positioning component and the second positioning component.

[0007] In one embodiment, the rotary seat is placed horizontally, and the first positioning component is assembled onto the rotary seat, such that the first spindle in the first positioning component is in a vertical state, including: The rotary seat is raised by a support member. The first positioning component includes a first receiving plate, a first mandrel, and a bushing. The first receiving plate is assembled on the lower part of the rotary seat, and the bushing is assembled on the upper part of the rotary seat. The first mandrel is inserted into the through hole of the bushing and the first receiving plate, so that the central axis of the first mandrel is coaxial with the rotation center axis of the rotary seat.

[0008] In one embodiment, inserting the first mandrel into the through hole of the bushing and the first receiving plate, such that the central axis of the first mandrel is coaxial with the rotational central axis of the rotary seat, includes: Adjust the position of the bushing so that the first mandrel can rotate relative to the bushing, and then lock the bushing.

[0009] In one embodiment, assembling the second positioning component onto the tool post spindle, such that the second spindle in the second positioning component is in a horizontal state, includes: The second positioning component includes a second receiving plate and a second mandrel that are coaxial and fixedly connected to each other. The second receiving plate is assembled on the tool post spindle and is coaxial with the tool post spindle. The second mandrel is horizontal and located above the first mandrel.

[0010] In one embodiment, raising the first mandrel and adjusting the position of the tool post spindle so that the slot at the upper end of the first mandrel engages with the second mandrel, so that the first mandrel and the second mandrel are orthogonal, includes: Using one upper side of the rotary table as a reference plane, a standard push block is placed on the reference plane. The standard push block is equipped with a torsion spring gauge, which points to the detection surface of the second spindle facing the reference plane. The standard push block is pushed to move horizontally on the reference plane so as to detect the parallelism between the second spindle and the reference plane through the torsion spring gauge. The position of the tool post spindle is adjusted until the parallelism meets the standard.

[0011] In one embodiment, adjusting the position of the tool post spindle so that the second receiving plate end face in the second positioning assembly abuts against the outer circular surface of the slot, so that the actual distance between the rotation center axis of the rotary seat and the tool center of the tool post spindle meets the design distance, includes: Based on the design distance, determine the radius machining dimension of the outer circular surface of the slot and the thickness machining dimension of the second receiving plate, so that the sum of the radius machining dimension of the outer circular surface of the slot and the thickness machining dimension of the second receiving plate is equal to the design distance.

[0012] In one embodiment, tightening the connecting screw to a third tightening level, which is greater than the second tightening level and is a complete tightening, includes: Push the standard push block horizontally on the reference plane again, and check the parallelism between the second mandrel and the reference plane using the torsion spring gauge. If the parallelism meets the standard, tighten the connecting bolt to the third locking degree.

[0013] In one embodiment, the multi-axis positioning method for the horizontal machine tool turret further includes: The tool post spindle and the rotary seat are fixedly connected to form a tool post assembly, and the tool post assembly is assembled onto the rotary support of the bedroom machine tool through the rotary seat; The bushing is fitted onto the rotary seat, and the first mandrel is inserted into the through hole of the bushing; The torsion spring gauge is applied to the first mandrel, and the horizontal machine tool is started to drive the rotating support to rotate. The coaxiality between the first mandrel and the rotating support is detected by the torsion spring gauge. Adjust the position of the tool holder assembly on the rotating support until the coaxiality meets the standard.

[0014] In one embodiment, the multi-axis positioning method for the horizontal machine tool turret further includes: The horizontal machine tool includes a column, and the rotary support is disposed on the column; Start the horizontal machine tool to move the column horizontally, and use the torsion spring gauge to detect the parallelism between the first mandrel and the machine bed.

[0015] Secondly, this application provides a multi-axis positioning device for a horizontal machine tool tool post, comprising: The first positioning component is used to connect the rotary seat, including a first receiving plate, a bushing and a first spindle; The second positioning component is used to connect the tool holder spindle, including a second receiving plate and a second spindle; The rotary seat is placed horizontally, and the tool post spindle is placed on the rotary seat and connected by connecting screws; The first receiving plate is used to assemble the lower part of the rotary seat from bottom to top, and the bushing is used to assemble the upper part of the rotary seat from top to bottom. The first mandrel is inserted into the through hole of the bushing and the first receiving plate so that the first mandrel is in a vertical state. The second mandrel is coaxially arranged and fixedly connected to the second receiving plate. The second receiving plate is assembled on the tool holder spindle so that the second mandrel is horizontal and located above the first mandrel. The first mandrel has a slot at its upper end, and the first mandrel can move upward relative to the bushing so that the slot can be inserted into the second mandrel so that the first mandrel and the second mandrel are orthogonal to each other. The outer circular surface of the slot abuts against the end face of the second receiving plate so that the actual distance between the rotation center axis of the rotary seat and the tool center of the tool holder spindle meets the design distance.

[0016] The advantages of this application compared to the prior art are: In this embodiment, by assembling a first positioning component on the rotary table and a second positioning component on the tool holder spindle, the first mandrel in the first positioning component is used as the extension of the rotary table's rotation center, and the second mandrel in the second positioning component is used as the extension of the tool holder spindle's center. By utilizing the cooperation (understood as coupling) between the first and second mandrels, the two major accuracy requirements are met: the rotary table's rotation center axis is orthogonal to the tool holder spindle's central axis, and the actual distance between the rotary table's rotation center axis and the tool center of the tool holder spindle meets the design distance. This achieves precise positioning between the tool holder spindle and the rotary table, improving the machining accuracy of the workpiece. Attached Figure Description

[0023] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.

[0024] Please refer to Figure 1 This document illustrates a flowchart of a multi-axis positioning method for a horizontal machine tool turret according to an embodiment of this application. In this embodiment, the multi-axis positioning method for a horizontal machine tool turret can be implemented using a positioning fixture, which can be a multi-axis positioning device for a horizontal machine tool turret. Please refer to [link / reference]. Figure 2 .

[0025] like Figure 1 As shown, the multi-axis positioning method for the tool post of this horizontal machine tool may include the following steps.

[0026] S110: The rotary seat 300 is placed horizontally, and the first positioning component 100 is assembled on the rotary seat 300, so that the first spindle 110 in the first positioning component 100 is in a vertical state.

[0027] In this embodiment, the rotary base 300 is part of the tool turret assembly and is used to mount on the rotary support of the horizontal machine tool. When it is necessary to adjust the angle of the tool turret assembly, the horizontal machine tool drives the rotary base 300 to rotate through the rotary support, thereby achieving the adjustment of the tool turret assembly angle. Specifically, the tool turret assembly includes the rotary base 300 and the tool turret spindle 400. The multi-axis positioning method for the horizontal machine tool tool turret in this embodiment is used for precise positioning between the rotary base 300 and the tool turret spindle 400, ensuring the machining accuracy of the workpiece when the tool turret assembly is used on the horizontal machine tool. The mutual positioning between the rotary base 300 and the tool turret spindle 400 is performed before the entire tool turret assembly is installed onto the horizontal machine tool.

[0028] Please refer to Figure 2 and Figure 3 First, the rotary seat 300 is placed horizontally. Specifically, during the machining of the rotary seat 300, a certain upper side of the rotary seat 300 in its horizontal position can be precision-machined to form a horizontal surface. This horizontal surface is used as a reference plane 320, and the accuracy of the rotary seat 300's horizontal placement is determined by using this reference plane 320 as a standard. Specifically, the degree of horizontality can be detected by applying a torsion spring gauge to the reference plane 320.

[0029] After the rotary seat 300 is placed horizontally, the first positioning component 100 is assembled onto the rotary seat 300, and the first spindle 110 in the first positioning component 100 is in a vertical state. Since the horizontality of the rotary seat 300 can be guaranteed, as long as the assembly accuracy between the first positioning component 100 and the rotary seat 300 is high, the verticality of the first spindle 110 can be guaranteed to meet the standard.

[0030] S120: Place the tool post spindle 400 on the rotary seat 300, and tighten the connecting screw 500 between the tool post spindle 400 and the rotary seat 300 to the first locking degree.

[0031] After the first positioning component 100 is assembled on the rotary base 300, the tool post spindle 400 can be placed on the rotary base 300. The tool post spindle 400 and the rotary base 300 are connected by connecting screws 500 (such as hex socket head cap screws). Both the tool post spindle 400 and the rotary base 300 need to have corresponding screw holes. However, at this time, it is only necessary to tighten the connecting screws 500 to the first locking degree. That is, the connecting screws 500 are not completely tightened directly. The first locking degree is a proper engagement, ensuring that the tool post spindle 400 will not easily detach from the rotary base 300. At this time, the tool post spindle 400 and the rotary base 300 are not completely fastened to each other, which provides freedom for adjusting the position of the tool post spindle 400 relative to the rotary base 300, facilitating subsequent positioning operations.

[0032] S130: The second positioning component 200 is assembled onto the tool holder spindle 400, so that the second spindle 210 in the second positioning component 200 is in a horizontal state.

[0033] After the tool post spindle 400 is substantially installed on the rotary table using the connecting screws 500 tightened to the first locking level (not fully tightened), the second positioning assembly 200 is assembled onto the tool post spindle 400, ensuring that the second spindle 210 within the second positioning assembly 200 is horizontal. The precise assembly of the second positioning assembly 200 onto the tool post spindle 400 makes the second spindle 210 an externally explicit component that reflects the horizontality of the tool post spindle 400. Positioning the second spindle 210 achieves the positioning of the tool post spindle 400, facilitating the detection of positioning accuracy and contributing to improved positioning accuracy of the tool post spindle 400 on the rotary table 300.

[0034] S140: Raise the first mandrel 110 and adjust the position of the tool post spindle 400 so that the slot 111 at the upper end of the first mandrel 110 is inserted into the second mandrel 210 so that the first mandrel 110 and the second mandrel 210 are orthogonal.

[0035] After the second positioning component 200 is assembled onto the tool holder spindle 400, the second spindle 210 in the second positioning component 200 becomes an extended explicit component that reflects the horizontality of the tool holder spindle 400. Specifically, in some embodiments, the second spindle 210 is preferably coaxially arranged with the central axis of the tool holder spindle 400, so the central axis of the second spindle 210 is an extension of the central axis of the tool holder spindle 400. The rotary seat 300 is equipped with the first positioning component 100, and the first spindle 110 in the first positioning component 100 becomes a component that reflects the verticality of the central axis of the rotary seat 300. Specifically, in some embodiments, the central axis of the first spindle 110 is preferably coaxially arranged with the rotational central axis 310 of the rotary seat 300, so the central axis of the first spindle 110 becomes an extension of the rotational central axis 310 of the rotary seat 300.

[0036] In this embodiment, the first mandrel 110 is raised and the position of the tool post spindle 400 relative to the rotary seat 300 is adjusted so that the slot 111 at the upper end of the first mandrel 110 can be inserted and engaged with the second mandrel 210. Specifically, the slot 111 opens upward and extends through the horizontal direction of the second mandrel 210, so that while the second mandrel 210 is inserted into the slot 111 from bottom to top, the second mandrel 210 passes horizontally through the slot 111. When the position of the tool post spindle 400 is adjusted, the second mandrel 210 moves along with the tool post spindle 400. When the second mandrel 210 can be fully inserted and engaged with the slot 111 at the upper end of the first mandrel 110 (understood as coupling), it is considered that the first mandrel 110 and the second mandrel 210 are mutually orthogonal.

[0037] Since the central axis of the first spindle 110 is essentially an extension of the rotational central axis 310 of the rotary seat 300, and the central axis of the second spindle 210 is essentially an extension of the central axis of the tool post spindle 400, when the first spindle 110 and the second spindle 210 are orthogonal, the rotational central axis 310 of the rotary seat 300 and the central axis of the tool post spindle 400 are orthogonal, thus achieving the initial positioning of the tool post spindle 400 on the rotary seat 300.

[0038] S150: Tighten the connecting screw 500 to a second tightening degree, which is greater than the first tightening degree.

[0039] Through S140, the tool post spindle 400 is initially positioned on the rotary seat 300. Then, the connecting screw 500 can be further tightened from the first locking level to the second locking level. The second locking level is greater than the first, but it is not completely tightened. Even though the assembly tightness of the tool post spindle 400 on the rotary seat 300 is improved to a certain extent, the tool post spindle 400 is not completely secured to the rotary seat 300. The tool post spindle 400 can still be adjusted relative to the rotary seat 300, but its degree of freedom is lower than that of the first locking level, and the adjustable position range is smaller, thus avoiding the destruction of the initial orthogonal positioning result already achieved.

[0040] S160: Adjust the position of the tool holder spindle 400 so that the end face of the second receiving plate 220 in the second positioning component 200 abuts against the outer circular surface 112 of the slot 111, so that the actual distance between the rotation center axis 310 of the rotary seat 300 and the tool center 410 of the tool holder spindle 400 meets the design distance.

[0041] Adjust the position of the tool post spindle 400 until the second spindle 210 and the slot 111 of the first spindle 110 are fully engaged, achieving orthogonal positioning between the central axis of the tool post spindle 400 and the rotational central axis 310 of the rotary seat 300. Then, continue adjusting the position of the tool post spindle 400 so that the end face of the second receiving plate 220 in the second assembly abuts against the outer circular surface 112 of the slot 111. During the design phase, there will be a design distance between the rotational central axis 310 of the rotary seat 300 and the tool center 410 of the tool post spindle 400. When actually assembling the rotary seat 300 and the tool post spindle 400 into a complete tool post assembly, the actual distance between the rotational central axis 310 of the rotary seat 300 and the tool center 410 of the tool post spindle 400 needs to meet the design distance.

[0042] In this embodiment, after the outer circular surface 112 of the upper end slot 111 of the first mandrel 110 abuts against the end face of the second receiving plate 220, the sum of the radius of the outer circular surface 112 and the thickness of the second receiving plate 220 is the actual distance between the rotation center axis 310 of the rotary seat 300 and the tool center 410 of the tool holder spindle 400. When machining the outer circular surface 112 of the upper end slot 111 of the first mandrel 110 and the second receiving plate 220, the machining dimensions of the radius of the outer circular surface 112 of the slot 111 and the machining dimensions of the thickness of the second receiving plate 220 are determined according to the known design distance. Therefore, as long as the outer circular surface 112 of the slot 111 is tightly abutted against the end face of the second receiving plate 220 during the positioning stage, the distance between the central axis of the first mandrel 110 and the tool center 410 of the tool holder spindle 400 is considered to be the design distance. Since the central axis of the first spindle 110 is an extension of the rotation center axis 310 of the rotary seat 300, it is assumed that the actual distance between the rotation center axis 310 of the rotary seat 300 and the tool center 410 of the tool post spindle 400 meets the design distance, thereby achieving further positioning between the tool post spindle 400 and the rotary seat 300.

[0043] S170: Tighten the connecting screw 500 to the third tightening level, which is greater than the second tightening level, and the third tightening level is fully tightened.

[0044] After initial and further positioning of the tool holder spindle 400 and rotary base 300 via steps S140 and S160, the relative positions of the tool holder spindle 400 and rotary base 300 are accurately positioned. Then, the connecting screw 500 is tightened to the third tightening level, which is greater than the second tightening level and represents a complete tightening. The connecting screw 500 is then thoroughly tightened, ensuring the tool holder spindle 400 is fully and securely mounted on the rotary base 300. Maintaining the precise positional relationship between the tool holder spindle 400 and rotary base 300 through the connecting screw 500 effectively improves the machining accuracy of the workpiece during use.

[0045] S180: Disassemble the first positioning component 100 and the second positioning component 200.

[0046] After fully tightening the connecting screw 500 in S170, the tool post spindle 400 is completely and securely assembled on the rotary seat 300. The tool post spindle 400 and the rotary seat 300 form a complete tool post assembly. At this time, the tool post assembly satisfies the two major accuracy requirements: the rotation center axis 310 of the rotary seat 300 is orthogonal to the central axis of the tool post spindle 400, and the actual distance between the rotation center axis 310 of the rotary seat 300 and the tool center 410 of the tool post spindle 400 meets the design distance. It can then be installed on a horizontal machine tool for use in machining workpieces.

[0047] Therefore, after assembling the complete tool post assembly, the first positioning component 100 and the second positioning component 200 need to be removed from the tool post assembly. After disassembly, the tool post assembly can be installed on the horizontal machine tool for use.

[0048] Therefore, in this embodiment, by assembling a first positioning component 100 on the rotary seat 300 and a second positioning component 200 on the tool holder spindle 400, the first spindle 110 in the first positioning component 100 is used as the extension of the rotation center of the rotary seat 300, and the second spindle 210 in the second positioning component 200 is used as the extension of the center of the tool holder spindle 400. By utilizing the cooperation (understood as coupling) between the first spindle 110 and the second spindle 210, the two major accuracy requirements are met: the rotation center axis 310 of the rotary seat 300 is orthogonal to the central axis of the tool holder spindle 400, and the actual distance between the rotation center axis 310 of the rotary seat 300 and the tool center 410 of the tool holder spindle 400 meets the design distance. This achieves precise positioning between the tool holder spindle 400 and the rotary seat 300, thereby improving the machining accuracy of the workpiece.

[0049] Preferably, S110 may specifically include: raising the rotary seat 300 by means of a support member, wherein the first positioning component 100 includes a first receiving plate 120, a first mandrel 110 and a bushing 130, assembling the first receiving plate 120 on the lower part of the rotary seat 300, assembling the bushing 130 on the upper part of the rotary seat 300, inserting the first mandrel 110 into the through hole of the bushing 130 and the first receiving plate 120, so that the central axis of the first mandrel 110 is coaxial with the rotation center axis 310 of the rotary seat 300.

[0050] In this embodiment, the horizontal position of the rotary seat 300 is maintained by a support member, which elevates the rotary seat 300, suspending its lower side in the air to facilitate the assembly of the first positioning component 100. Specifically, wooden blocks can be placed under the rotary seat 300. In this embodiment, the first positioning component 100 includes a first receiving plate 120, a first mandrel 110, and a bushing 130. Specifically, the first receiving plate 120 is assembled from bottom to top on the lower part of the rotary seat 300, and the bushing 130 is assembled from top to bottom on the upper part of the rotary seat 300. Both the first receiving plate 120 and the bushing 130 have through holes coaxial with the rotation center axis 310 of the rotary seat 300. Then, the first mandrel 110 is inserted into the through holes of the first receiving plate 120 and the bushing 130, so that the central axis of the first mandrel 110 is coaxial with the rotation center axis 310 of the rotary seat 300, making the first mandrel 110 an extension of the rotation center of the rotary seat 300. The positioning of the rotation center of the rotary seat 300 is achieved by positioning the first mandrel 110, which is convenient for operation and more explicit, and can effectively improve the positioning accuracy.

[0051] Furthermore, S110 may specifically include: adjusting the position of the bushing 130 so that the first spindle 110 can rotate relative to the bushing 130, and then locking the bushing 130.

[0052] In this embodiment, when assembling the bushing 130 onto the upper part of the rotary seat 300, the screws on the bushing 130 can be not fully tightened first. After inserting the first mandrel 110 into the through hole of the bushing 130, the position of the bushing 130 is adjusted so that the first mandrel 110 can easily and flexibly rotate relative to the bushing 130. This proves that the bushing 130 has been adjusted to be coaxial with the first mandrel 110, and there will be no obvious relative friction on either side due to the distance being too close to the first mandrel 110. At this time, it can be ensured that both the bushing 130 and the first mandrel 110 are coaxial with the rotation center axis 310 of the rotary seat 300, thereby ensuring the positional accuracy of the first mandrel 110 on the rotary seat 300 and improving the subsequent positioning accuracy.

[0053] Preferably, S130 may specifically include: the second positioning component 200 includes a second receiving plate 220 and a second spindle 210 that are coaxial and fixedly connected to each other, the second receiving plate 220 is assembled on the tool holder spindle 400 and coaxial with the tool holder spindle 400, and the second spindle 210 is horizontal and located above the first spindle 110.

[0054] In this embodiment, the tool holder spindle 400 is mounted on the rotary base 300 in step S120, but the connecting screw 500 is not fully tightened, allowing adjustment of the position of the tool holder spindle 400 relative to the rotary base 300. Specifically, in step S130, the second positioning component 200 includes a second receiving plate 220 and a second spindle 210 that are coaxially and fixedly connected to each other. To ensure accuracy, the second receiving plate 220 and the second spindle 210 can preferably be integrally formed, and then the second receiving plate 220 is assembled to the tool holder spindle 400 and coaxially positioned with it. At this time, the second spindle 210 is horizontal and located above the first spindle 110. The second spindle 210 is also coaxial with the tool holder spindle 400, so the second spindle 210 becomes an extension of the center of the tool holder spindle 400. Positioning the tool holder spindle 400 can be achieved by positioning the second spindle 210, which is convenient for operation, more explicit, and can effectively improve positioning accuracy.

[0055] Preferably, please refer to Figure 4S140 may specifically include: taking one upper side of the rotary seat 300 as a reference plane 320, placing a standard push block on the reference plane 320, the standard push block being provided with a torsion spring gauge, the torsion spring gauge pointing to the detection surface of the second spindle 210 facing the reference plane 320, pushing the standard push block to move horizontally on the reference plane 320, so as to detect the parallelism between the second spindle 210 and the reference plane 320 through the torsion spring gauge, and adjusting the position of the tool post spindle 400 until the parallelism meets the standard.

[0056] In S140, the first spindle 110 is raised and the position of the tool post spindle 400 is adjusted so that the slot 111 at the upper end of the first spindle 110 is inserted into the second spindle 210. The shape of the slot 111 has been described above. When they are fully inserted, the first spindle 110 and the second spindle 210 are considered to be orthogonal, thus achieving orthogonality between the rotation center axis 310 of the rotary seat 300 and the center axis of the tool post spindle 400.

[0057] In this embodiment, whether the first spindle 110 and the second spindle 210 are completely orthogonal is preferably determined by detecting parallelism. Specifically, one upper side of the rotary seat 300 is precision machined during the machining stage to make it a reference plane 320. A standard push block is placed on the reference plane 320, and the standard push block is equipped with a torsion spring gauge. The side of the second spindle 210 facing the reference plane 320 (i.e., downward) is used as the detection surface, and the torsion spring gauge points to this detection surface of the second spindle 210. Then, the standard push block is pushed to move horizontally on the reference plane 320, so that the torsion spring gauge detects the parallelism between the second spindle 210 and the reference plane 320. During this process, the position of the tool post spindle 400 can be adjusted according to the detection result of the torsion spring gauge until the parallelism detected by the torsion spring gauge meets the standard. At this point, the adjustment of the position of the tool post spindle 400 is stopped, and it is considered that the first spindle 110 and the second spindle 210 have achieved complete mutual orthogonality.

[0058] Preferably, S160 may specifically include: determining the radius machining dimension of the outer circular surface 112 of the slot 111 and the thickness machining dimension of the second receiving plate 220 based on the design distance, such that the sum of the radius machining dimension of the outer circular surface 112 of the slot 111 and the thickness machining dimension of the second receiving plate 220 is equal to the design distance.

[0059] During the design phase, the design distance between the rotation center axis 310 of the rotary seat 300 and the tool center 410 of the tool post spindle 400 is obtained. Then, based on this design distance, the radius machining dimension of the outer circular surface 112 of the slot 111 and the thickness machining dimension of the second receiving plate 220 are determined, so that the sum of the radius machining dimension of the outer circular surface 112 of the slot 111 and the thickness machining dimension of the second receiving plate 220 is equal to the design distance. In this way, during positioning, it is only necessary to make the outer circular surface 112 of the slot 111 tightly abut against the end face of the second receiving plate 220, so that the actual distance between the central axis of the first spindle 110 and the tool center 410 of the tool holder spindle 400 meets the design distance. Since the central axis of the first spindle 110 is the extension of the rotation center axis 310 of the rotary seat 300, it is assumed that the actual distance between the rotation center axis 310 of the rotary seat 300 and the tool center 410 of the tool holder spindle 400 meets the design distance, thereby achieving further positioning between the rotary seat 300 and the tool holder spindle 400.

[0060] Preferably, S170 may specifically include: pushing the standard push block to move horizontally on the reference plane 320 again, checking the parallelism between the second spindle 210 and the reference plane 320 by the torsion spring gauge, and tightening the connecting bolt to the third locking degree if the parallelism meets the standard.

[0061] After initial and further positioning of the tool post spindle 400 and rotary base 300 are achieved through steps S140 and S160, the relative positions of the tool post spindle 400 and rotary base 300 are accurately positioned. Therefore, in step S170, the connecting screw 500 can be tightened to the third tightening level, which is greater than the second tightening level and is a complete tightening, thereby completely securing the tool post spindle 400 to the rotary base 300.

[0062] However, during the process of adjusting the position of the tool post spindle 400 to ensure that the second receiving plate 220 and the outer circular surface 112 of the slot 111 are in close contact, the previously achieved result of the first mandrel 110 and the second mandrel 210 being orthogonal to each other may be affected. Therefore, in this embodiment, it is preferable that before tightening the connecting screw 500 to the third tightening degree, the standard push block is pushed horizontally on the reference plane 320 again, and the parallelism between the second mandrel 210 and the reference plane 320 is checked again using a torsion spring gauge. If the parallelism meets the standard, the test is ended, and the connecting screw 500 is then fully tightened; if the parallelism does not meet the standard, the position of the tool post spindle 400 is readjusted until the parallelism meets the standard, and the outer circular surface 112 of the slot 111 is checked to ensure that it is in close contact with the end face of the second receiving plate 220. When both indicators meet the standard, the connecting screw 500 is then fully tightened.

[0063] In this embodiment, the tool post spindle 400 and the rotary table 300 are fully assembled to form a complete tool post assembly. The first positioning component 100 and the second positioning component 200 play a role in precisely positioning each other during the assembly process of the tool post spindle 400 and the rotary table 300. After the tool post assembly is assembled, the first positioning component 100 and the second positioning component 200 need to be disassembled, and then the tool post assembly is assembled onto a horizontal machine tool for use. The tool post assembly also needs to be positioned between itself and the horizontal machine tool to ensure the machining accuracy in subsequent processing.

[0064] Therefore, please refer to Figure 5 Preferably, a multi-axis positioning method for a horizontal machine tool tool post according to an embodiment of this application may further include: the tool post spindle 400 and the rotary seat 300 are fixedly connected to form a tool post assembly; the tool post assembly is assembled onto the rotary support of the horizontal machine tool via the rotary seat 300; the bushing 130 is assembled onto the rotary seat 300; the first spindle 110 is inserted into the through hole of the bushing 130; the torsion spring gauge is applied to the first spindle 110, the horizontal machine tool is started to drive the rotary support to rotate, and the coaxiality of the first spindle 110 and the rotary support is detected by the torsion spring gauge; the position of the tool post assembly on the rotary support is adjusted until the coaxiality meets the standard.

[0065] Specifically, when the tool post assembly is assembled onto the horizontal machine tool, the rotary seat 300 changes from a horizontal position to a vertical position. The tool post assembly is installed onto the rotating support of the horizontal machine tool through the rotary seat 300. During the use of the horizontal machine tool, when it is necessary to adjust the angle of the tool post assembly, the rotating support drives the tool post assembly to rotate a certain angle.

[0066] After the tool post assembly is assembled onto the rotary support of the horizontal machine tool via the rotary base 300, the bushing 130 is reassembled onto the rotary base 300 (in the same position as before), and the first mandrel 110 is reinserted into the through hole of the bushing 130. A torsion spring gauge is then applied to the first mandrel 110. The horizontal machine tool is then started to rotate the rotary support, and the coaxiality between the first mandrel 110 and the rotary support is checked using the torsion spring gauge. If the coaxiality is not up to standard, the screws connecting the rotary base 300 and the rotary support are loosened, the position of the tool post assembly on the rotary support is adjusted, the screws are tightened, and the horizontal machine tool is restarted to rotate the tool post assembly. The coaxiality between the first mandrel 110 and the rotary support is checked again using the torsion spring gauge. This process can be repeated until the coaxiality is up to standard, thus improving the machining accuracy of the tool post assembly on the workpiece.

[0067] Furthermore, in a multi-axis positioning method for a horizontal machine tool turret according to an embodiment of this application, after detecting the coaxiality of the first spindle 110 and the rotating support, the method may further include: the horizontal machine tool includes a column 610, and the rotating support is disposed on the column 610; the horizontal machine tool is started to drive the column 610 to move horizontally, and the parallelism between the first spindle 110 and the bed 620 is detected by the torsion spring gauge.

[0068] The torsion spring gauge still acts on the first spindle 110, starting the horizontal machine tool to drive the column 610 to move horizontally relative to the bed 620. During this process, the torsion spring gauge detects the parallelism between the first spindle 110 and the bed 620 to ensure the machining accuracy of the workpiece during the subsequent use of the tool post assembly.

[0069] Please refer to Figure 2 The diagram shows a schematic of a multi-axis positioning device for a horizontal machine tool tool post provided in an embodiment of this application.

[0070] like Figure 2 As shown in the figure, an embodiment of this application provides a multi-axis positioning device for a horizontal machine tool tool post, which may include: The first positioning component 100 is used to connect the rotary seat 300 and includes a first receiving plate 120, a bushing 130 and a first spindle 110. The second positioning component 200 is used to connect the tool holder spindle 400, and includes a second receiving plate 220 and a second spindle 210. The rotary seat 300 is placed horizontally, and the tool post spindle 400 is placed on the rotary seat 300 and connected by connecting screws 500. The first receiving plate 120 is used to be assembled from bottom to top on the lower part of the rotary seat 300, and the bushing 130 is used to be assembled from top to bottom on the upper part of the rotary seat 300. The first mandrel 110 is inserted into the through hole of the bushing 130 and the first receiving plate 120 so that the first mandrel 110 is in a vertical state. The second spindle 210 and the second receiving plate 220 are coaxially arranged and fixedly connected. The second receiving plate 220 is assembled on the tool post spindle 400 so that the second spindle 210 is horizontal and located above the first spindle 110. The first spindle 110 has a slot 111 at its upper end. The first spindle 110 can move upward relative to the bushing 130 so that the slot 111 can be inserted into the second spindle 210 so that the first spindle 110 and the second spindle 210 are orthogonal to each other. The outer circular surface 112 of the slot 111 abuts against the end face of the second receiving plate 220 so that the actual distance between the rotation center axis 310 of the rotary seat 300 and the tool center 410 of the tool holder spindle 400 meets the design distance.

[0071] The horizontal machine tool tool post multi-axis positioning device provided in this application embodiment can be used to position the tool post spindle 400 and rotary seat 300 in the tool post assembly using the horizontal machine tool tool post multi-axis positioning method, and can also position the tool post assembly on the horizontal machine tool, thereby effectively improving the machining accuracy of the tool post assembly on the workpiece.
